Back up your Game Save before using any EMMI cheat code
the EMMI invincible cheat and Optantic NO KO cheat one of them if saved while they are enabled, you render your game save useless
you no longer can use L button to Aim in any direction, EMMI will be invincible to all damage even after a full console restart and cheats are off, i do have a master cheat list with all Author cheats, including speedfly, also Kaito B deleted his Unlock all skills cheat, it was already broken, his infinite Auto Beam Charge conflicts with invisible cloak, EMMI will instantly find you, there is no Turn off Code, make an off code for it if you enter AMMI zones
one other cheat will make Key Items or upgrades impossible to pick up
GamerJin made new amazing cheats, maybe JinKazama0012 can steal them again and take credits

game can be completed in less then 5 hours, a new Walk-through was posted in Youtube
